Read and understand all instructions on this sheet and in the Owner’s manual before
plugging any power cord into an electrical outlet. This information sheet will help you
identify the voltage and cords you need where you live and will outline requirements
for:
• Grounded, dedicated lines
• Voltage
• Power cords
• Power adapters
• Extension cords
DANGER: Improper connection of the equipment grounding conductor can result in risk of electric
shock. Check with a qualified electrician or service provider if you are in doubt as to
whether the equipment is properly grounded or installed on a dedicated line. Seek a
qualified electrician to perform any modifications to the cord or plug. Mobility Research
is not responsible for injuries or damages as a result of cord or plug modification.
CAUTION: Place cords away from heat (such as baseboards). Use care to arrange any cord so it
doesn’t become an obstacle.
Extension Cords
Do not use an extension cord to supply power to any GaitKeeper treadmill.
GaitKeeper equipment must be grounded. If it should malfunction or break down,
grounding provides a path of least resistance for electric current to reduce the risk of
electric shock. GaitKeeper cords (except for cycle adapters) have an equipment
grounding conductor and a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local
codes and ordinances where you live. Do not use a ground plug adapter to adapt the
power cord to a non-grounded outlet. Do not use a GFCI outlet or GFCI circuit breaker. A
dedicated line will assure that adequate power is available for safe operation over the
life of your GaitKeeper treadmill.
Voltage
Voltage required for your unit is located on the serial number decal (usually on the front
of the unit). Depending on where you live voltage requirements differ.

WARNING: To reduce the risk of burns, fire, electric shock or injury, it is imperative to connect each product
to a properly grounded electrical outlet. A risk of electrical shock may result from improper connection of the
equipment’s grounding conductor. Check with a qualified electrician if you are unsure about proper
grounding techniques. Do not modify the plug provided with this product. If it will not fit an electrical outlet,
have a proper outlet installed by a qualified electrician. Your MOBILITY RESEARCH Fitness product must be
properly grounded to reduce risk of shock if the treadmill malfunctions. Your treadmill is equipped with an
electrical cord, which includes an equipment grounding conductor and a grounding plug. The plug must be
inserted into an outlet that has been properly installed and grounded in accordance with all local codes and
ordinances. A temporary adapter cannot be used to connect this plug to a two-pole receptacle in North
America. If a properly grounded 120 Volt/15 Amp outlet is not available, a qualified electrician must install
one.

Dirt, dust, and hair can block air inlets and accumulate on the running belt. Please vacuum underneath your
treadmill on a monthly basis to prevent excess build-up of dirt that can get sucked up and get into the inner
workings under the motor cover. Every other month, you should remove the motor cover and carefully
vacuum out dirt and hair that may accumulate. UNPLUG THE POWER CORD BEFORE THIS TASK. (Use the chart
at the beginning of the manual to record your maintenance)
Tread-belt Tension Adjustment - Belt tension is not critical for most users. It is very important though for
joggers and runners in order to provide a smooth, steady running surface. Adjustment must be made from
the rear roller with the 6mm Allen wrench provided in the parts package. The adjustment bolts are located at
the end of the step rails as shown in the diagram below.
Tighten the rear roller only enough to prevent slippage at the
front roller. Turn the tread-belt tension adjusting bolts 1/4 turn
each and inspect for proper tension by walking on the belt and
making sure it is not slipping or hesitating with each step. When
an adjustment is made to the belt tension, you must be sure to
turn the bolts on both sides evenly or the belt could start
tracking to one side instead of running in the middle of the
deck.
DO NOT OVERTIGHTEN –Over tightening will cause belt damage and premature bearing failure. If you
tighten the belt a lot and it still slips, the problem could actually be the drive belt - located under the motor
cover - that connects the motor to the front roller. If that belt is loose it feels similar to the walking belt being
loose. Tightening the motor belt should be done by a trained service person.
The treadmill is designed so that the tread-belt remains reasonably centered while in use. It is normal for
some belts to drift near one side while in use, depending on a user’s gait and if they favor one leg. But if
during use the belt continues to move toward one side, adjustments are necessary.
If the belt is too close to the right side, turn the bolt counter-clockwise. The belt may require periodic
tracking adjustment depending on use and walking/running characteristics. Some users may affect tracking
differently. Expect to make adjustments as required to center the tread-belt. Adjustments will become less of
a maintenance concern as the belt is used. Proper belt tracking is an owner responsibility common with all
treadmills.
A 6mm Allen wrench is provided for this adjustment. Make
tracking adjustments on the left side bolt. Set belt speed at 3
mph. Be aware that a small adjustment can make a dramatic
difference which may not be apparent right away. If the belt is
too close to the left side, then turn the bolt only a 1/4 turn to
the right (clockwise) and wait a few minutes for the belt to
adjust itself. Continue to make 1/4 turns until the belt stabilizes
in the center of the running deck.

11
Damage to the running belt resulting from improper tracking / tension adjustments is not covered under the
limited warranty.
1. Every 2-3 months (or after 90 hours of use) check to see if the deck is still sufficiently lubed. A dry or
sticky deck will need to be cleaned and lubed.
2. Clean between the belt and deck to remove any debris that may be trapped. Use a clean, non-fraying rag.
Halfway between the end of the treadmill and motor cover, slide the rag under the belt until you can
grasp it at both sides. Drag the garment the entire length of the deck 1-2 times. When you’ve ascertained
that the belt is obstruction free, you can begin the lubing process.
3. We supply you with a tube of silicone based lube. Do not lubricate with anything other than approved
lube - as spray or water based lube can dry quickly or damage your machine. You will need to use a
significant amount of lube on your machine.
4. Turn the power switch off and unplug the power cord from the wall outlet
5. Measure 18” from the edge of the motor cover; kneel down and reach under the belt approximately 4-
6” from one edge. Squirt a line of lubricant in a slight “S” pattern 1/8’th wide and 15” long. Repeat on the
other side.
6. Plug the electrical cord back into the outlet and turn the power switch on.
7. Walk on the belt at a moderate speed for five minutes to evenly distribute the silicone lube.
1. On the main screen press and hold the SELECT button for 3 seconds to enter the lube message reset
mode.
2. Press the START key to reset.
3. Press the STOP key to return to main display.
